go-fuse 是fuse 的包裝，我們可以用來開發fuse 文件系統，以下是一個簡單的學習
項目准備
- go mod
go mod init demoapp
- 添加依賴
go get github.com/hanwen/go-fuse/v2
- 簡單代碼
main.go
package main
import (
"context"
"flag"
"log"
"syscall"
"github.com/hanwen/go-fuse/v2/fs"
"github.com/hanwen/go-fuse/v2/fuse"
)
type HelloRoot struct {
fs.Inode
}
func (r *HelloRoot) OnAdd(ctx context.Context) {
ch := r.NewPersistentInode(
ctx, &fs.MemRegularFile{
Data: []byte("file.txt"),
Attr: fuse.Attr{
Mode: 0644,
},
}, fs.StableAttr{Ino: 2})
r.AddChild("file.txt", ch, false)
}
func (r *HelloRoot) Getattr(ctx context.Context, fh fs.FileHandle, out *fuse.AttrOut) syscall.Errno {
out.Mode = 0755
return 0
}
var _ = (fs.NodeGetattrer)((*HelloRoot)(nil))
var _ = (fs.NodeOnAdder)((*HelloRoot)(nil))
func main() {
debug := flag.Bool("debug", false, "print debug data")
flag.Parse()
if len(flag.Args()) < 1 {
log.Fatal("Usage:\n hello MOUNTPOINT")
}
opts := &fs.Options{}
opts.Debug = *debug
server, err := fs.Mount(flag.Arg(0), &HelloRoot{}, opts)
if err != nil {
log.Fatalf("Mount fail: %v\n", err)
}
server.Wait()
}
構建&&運行
- 構建
go build
- 運行
mkdir /demo
./demoapp /demo
- 效果
